If reverse polarity is accidentally applied to the input, to ensure reverse input protection, always connect an external fast blow input fuse in series with the +Vin input. www.murata-ps.com/support WDC_IRV300 Series.A01.D29 Page 12 of 21 IRV300 Series PRELIMINARY 300W 10:1 Ultra Wide Input Chassis-Mount Isolated DC-DC Converter TYPICAL PERFORMANCE DATA, IRV300-54 Start-up Waveform Start-up Waveform TBD TBD Hold Up/Interruption Time: Measured hold up time with 54Vo/200W Hold Up/Interruption Time: Measured hold up time with 54Vo/300W TBD TBD Power Efficiency vs Load Overload Protection at Vin = 110V @ 22C TBD TBD www.murata-ps.com/support WDC_IRV300 Series.A01.D29 Page 13 of 21 IRV300 Series PRELIMINARY 300W 10:1 Ultra Wide Input Chassis-Mount Isolated DC-DC Converter TYPICAL PERFORMANCE DATA, IRV300-54 Output Ripple & Noise (TBDmVp-p) Transient Response Vin = 110V (Ch1), Vout = 54V (Ch3), Iout = 5.5A (Ch4), 5us/div.

When input voltage drops to lower than VIN_OFF (refer to PUL section) but is higher than 14.4V, a 100mS timer is set. If the input voltage doesn't recover to above VIN_ON in 100mS, the timer will be reset, the converter will shut down. If the input voltage drops lower than 14.4V, Hold Up circuit starts to work to keep the output uninterrupted. The converter will shut down if the output voltage starts to drop and cause the open-collector P_OK+ signal to be released (to open status) or the timer is reset.

The resistor value could also be calculated based on the preferred turn-off voltage that customers select for battery protection. R_PUL = 953.62/(VIN_OFF-14.4) Where R_PUL is PUL resistor in k, VIN_OFF is the turn-off voltage in Volt. Corresponding turn-on voltage VIN_ON is VIN_ON = 15.95(R_PUL+66.23)/R_PUL When input voltage drops lower than VIN_OFF, the converter will continue operating 100mS before turning off the output. When input voltage drops lower than 14.4V, the converter enters input interruption mode. The hold-up circuit will keep the output uninterrupted for no less than 10mS under nominal load output. The converter will be shut down if input voltage is not recovered to above 16V afterward. P_OK+ Signal www.murata-ps.com/support WDC_IRV300 Series.A01.D29 Page 17 of 21 PRELIMINARY IRV300 Series 300W 10:1 Ultra Wide Input Chassis-Mount Isolated DC-DC Converter ORing FET Option ORing FET feature allows outputs of multiple units to be connected in parallel when high output power is required or when N+1 redundancy operation is required. The units in parallel have passive current sharing. To put units in parallel operation, load line has to be enabled on each unit by connecting the LL_EN pin to VOUTN pin on the control connector. The output voltage will drop with the increase of output current by 10mV/A for 12V and 24V model, 100mV/A for 54V model. The output power cables should have the same gauge and length for each unit from the output connector to the meeting points to the load to ensure balanced power output for each unit.

When a resistor is connected between VO_UP and VO_ADJ (PIN 3), the output voltage will be set to a value that is higher than nominal voltage (12V for IRV300-12, 24V for IRV300-24). When the connected resistor is zero (short-circuiting PIN 1 and PIN 3), the output voltage is set to maximum (13.8V for IRV300-12, 26.4V for IRV300-24 and 57V for IRV300-54). PIN 2: P_OK+, open collector output . When the output voltage is higher than 10.5V for IRV300-12 (20.5V for IRV300-24 and 43.8V for IRV300-54), the voltage between P_OK+ (PIN 2) and VOutN (PIN 4) is pull down to less than 0.8V. PIN 3: VO_ADJ, for output voltage adjustment. Used with PIN 1 or PIN 5 to set the output voltage higher or lower than nominal voltage. PIN 4: VOUTN, used with P_OK+ (PIN 2) for output voltage status. This pin is internally connected to the negative terminal of the output connector. PIN 5: VO_DOWN, for output voltage adjustment. When a resistor is connected between VO_DOWN and VO_ADJ (PIN3), the output voltage will be set to a value that is lower than nominal voltage. When the connected resistor is zero (short-circuiting PIN5 and PIN3), the output voltage is set to minimum (11 for IRV300-12, 21.6V for IRV300-24, 47V for IRV300-54). PIN 6: LL_EN, for units with output ORing feature. Connect this pin to VOUTN (PIN 4) will enable output voltage droop with the increase of load current. This pin must be connected to VOUTN (PIN 4) before connecting outputs in parallel and enabling the ORing function. PIN 7: and PIN 8: No connection PIN 9: PUL1 and PIN 10: PUL2, for Programmable Under voltage Lockout (PUL). PIN 11: ON/OFF+, for output inhibit. Output is OFF when this pin is pull down to lower than 0.8V with reference to VINN (PIN 12). For output ON state, leave this pin open or connect and keep its voltage higher than 4V.
